EXCLUSIVE: SFPD promotions questioned by some police union members

SAN FRANCISCO (KGO) -- ABC7 News has learned that the San Francisco Police Officers Association has sent a blistering letter to Chief William Scott in the wake of recent department promotions. Many of its members, the union leadership says, believe the process is flawed.

The letter from the police union was sent to Chief William Scott after the department released the list of promotions a couple of weeks ago.

"I've never seen it this bad as long as I've been in this Department, which is twenty five years," said Tony Montoya, who heads the SFPOA. "I've never seen the department jump around so much to pick up certain candidates over others."

Promotions to sergeants, lieutenants and captains are based on civil service exams.
